It appears that current head (r11743) of Subversion behaves a bit
differently. The 'svn status' never shows ~, instead it just gives an
error. But, 'svn revert' works!

I think it's still a minor bug that the parent's .svn/entries file is
left with the entry for the new directory, but that bug is fairly
minor, given that 'svn revert' works on the bad directory and
correctly cleans up the parent's .svn/entries file.

So I'd say, file an issue, mark it as a P4 defect, put "bite-sized" in
the keywords field, and drop the issue in the 'unscheduled' milestone.

Here's the script I used to discover the different r11743 behavior:


### Edit these as necessary:

if [ -d wc ]; then
   (cd wc; rmdir bad)

rm -rf wc repos

${SVNADMIN} create repos
${SVN} mkdir -m "Create a top-level directory." file://`pwd`/repos/trunk

${SVN} co file://`pwd`/repos/trunk/ wc

cd wc

mkdir bad
chmod -r bad

echo ""
echo "Attempt to 'svn add' the bad directory:"
${SVN} add bad

echo ""
echo "Adding it failed. Try 'svn status':"
${SVN} st

echo ""
echo "Hmmm, what about 'svn status -v':"
${SVN} st -v

echo ""
echo "Yuck. But we can revert it:"
${SVN} revert bad

echo ""
echo "Now 'svn status -v' succeeds normally:"
${SVN} st -v

echo ""
echo "Done."
